Said prior application Vdiscloses a machine wherein thesuccession f hooks is advanced edg'ewise and in a step by F step manner,With the rounded backs of the 0 boo is beneath, and the successive bookscar# ried ina succession of clamps connected in a train; but the presentinvention is not con# fined to use with suchtype of machine, since 'hebook might be carried With it'slb'a'c'k above, U and by means other thana train-df 'clamps for the guidance and advancing movement of thebooks,'\vhich might in some cases be continus ons in character, althoughpreferably intermittent as in said application. The present invention,like the prior application, is preferably automatic, but is not confined,to an ap-V paratus wherein the preceding gluing and the succeedingbacklining `operations are automatic, vsince the present invention Visdirected more especially to the headbanding step'.v

The general object of thev present invention is to improve theeificiencyand the accuracy.

of foperation in the application of headbands to round back or otherbooks. A special vob# vject is to improve the devices handling the smallheadbands Y or strips and accurately alining or registering them to'eachbo'o'kd-ur-T ing application thereto.

Referring first to certain `general parts;` eachlbookfclamp 10 maycomprise a-front clampplate'll and aback clamp plate'i12, the successiveclamps being hinged vor articu-latedrtog'ether ina Well-known mannerandguided on longitudinal elements generally indicated at 13. Each backclamp `plate may advance toward the rightiuea xd path; Each front'clamp*plateis; slidingly fittedr tothe back yplate by a spring pressed devicev14, tending to hold 'the clamp plates pressed strongly upon the book B,but permittingV separation or frontwardy movement of the front plate-toreceive and discharge the book.

As is usual in clamp train machines; each book 'B is preferablyregistered intli'e clar'rp by actual Contact With some partV of 'theclamp', for example-with thedevice 14, or by a-special positioning orgag-ing '15,',arl rangednear the're'ar' or left end of the-clamp; theclamps being movable' toward the' infastep by step manner, each' bookbeingy held in its clamp with its rear or left edge'Y This may be due toslight variations or lost.

in contact with the pin 15, and with its rounded back extendinglongitudinally inV the direction of book travel and projecting bothplates of each clamp, and there iriayV be a' second pair'of `apertures11i V spaced therefrom so that the pin caribe shifted from one pair ofapertures Ato the other, according to` whether the machine is handlingrelatively short or long books; so that a short book may take a positionsomewhere near the iniddle of the clamp.

1n the drawings the d l carrying krelatively short books vB, their rearedgescontacting the pins 15 in the apertures 16, but other means mavv beemployed for holding and advancing the books from po- -sition toposition. lWhatevcr type or book holding or conveying means is employedthere is a likelihood of the successive books coming occasionally tothe. operating place orzstation in not exactly the correct position.`

motion in respect to. the travelof therbook advancing means to theheadbanding posi, tion, or it may be due to accidental variation` of theposition of each book in the'clanip or other'advancing means. Anyfsuchvariation inl longitudinal position, even though relatively small inamount, may be highly objectionable in connection with the applica-,tion of theheadbands to the books, as it is practically vital that eachheadband, being an ornamentalstrip or finish to each book back, shall be`correctly registered or positioned with relation to the topV and bottomends of the book, that is, to the forward and "rearward ends of thebook-.held and advanced in the manner disclosed. -With the presentinvention this requirement is met by a construction oflieadbandingmechanism wherein, during the pausey of each book, the

Vmechanism is caused toadjust itself 'to the book, through one or tvofeelers or contacterswhich detect and determine the position of one orboth ends of each book, and thereupon control the headband applyingdevices or the headbands themselves so that the headbands will bepositioned upon the books ,inv

the exactly correct locations desired, giving a uniform and satisfactoryproduct. The drive of the conveyor or clamp train may bevcoordinatedwith the headbanding mechanism as in the prior application,through a main shaft 19, preferably continuously ro-v standards arebrackets 21 giving support to annaxle 22 on which are mounted a pair ofclamps are shown asV supply spools 23 carrying the headband sup- Y plystrip H. The standards extend up- V- shapeiior 'concave forming member26 Vwhich presses a substantial portion or the entire length of the'headband upwardly firmlyV against the rounded book back, and a holder orsuction member 27 in the formv of ahead or' narrow nozzle adapted toreceive', and hold eachindividual headbandV during the movenient orlifting thereof to the book but preferablyzeasily yieldable as theshaper comes into action. The'combined elements 26 and 27 are shownmounted on` a carriage 28 or 23a, the latter at'the right or forward endof the mechanism, the, two carriages being arranged `to rise anddescend, also to swing inwardly and outwardly, that is, backwardlyandfrontwardly, in unison, aswill be described. Each carriage iscontinued downwardly as an extension or armV 29 or 29:L i

these terminating in ahub 30 Vor 30@ botli mounted on an axle systemarranged to rise and descend. f

The axle of thecarriagehubs30, may have the following specialconstruction toV permit adjustments for varying book lengths. rllhe lefthub 30 is mounted on a hollow axle part or sleeve 31, between collars 32held by set screws 33, the lsleeve and collars being non- Vrotatable butthe hub able to rock thereon, and` the hub beingV adjustablelongitudinally byl loosening the set screws and resetting the collarsaccording to the setting ofthe pin 15 in the book clamp. The hub 30L isconfined between collars 32a pinned to an axle part 3ft which at itsleft end is extended, reduced and` threaded at 35, this extensionpassing through the hollow axle part 3l and having screw engagementtherewith. Upon turning the axle part 34, 35 it will adjust itselfrightward or leftward and correspondingly vadjust the right carriage28a.

j For conveniently adjusting thecarriage 28a to any desired position,according to the varying lengths of books, and at the same time makingcertainV other adjustments to' correspond, a threaded shaft 37 is shown,carrying a hand wheel 38 at its right end, and

turning in a bracket`39., The shaft may be engaged by a nut 40, thusshifted Vright and left to adjust the severing and feeding devices aswill be described. The threads on the shaft4 37 may have the same pitchas those on the axle 35, and they may be connected to turn in unison asfollows. On the shaft 37- is to and in turn connectedlby a sprocketVchain 47 with a sprocket 48 which turns the axle partk 34. By thisarrangement theturning. of the hand wheel 38 effects the adjustment.

of the hubk and carriage 28a, adapting the mechanism tothe length of thebook. The rising and falling movements of the axle sys- 'tem 31-35 andthe carriages will be laterA described. Y

Corresponding withv the threaded shaft 37 which shifts the nut 4() toadjust thefeeding and severing devices atth'e right, there isA shown atthe left a threaded shaft 51 mounted in a b-racket 52 and having a head53 by which it can be turned by wrench, the shaft engaging a nut 54 fromwhich the severing and-feeding devices vtake their adjustment.

described. These two complementary adjustments at the left end are notmade so conveniently as those eHected by the hand wheel 38 at the rightend,or the reason that' .the

shift of thepin 15 in the clamp is rarely necessary, while variousmiscellaneous variations of book length may be wholly taken care Y ofbythe adjustments at the right or forward end by the hand wheel 38 asdescribed.

Returning to the applying device, :supported on each carriage,consisting of shaper and suction holder, the Shaper 26 is shown asa thinplate or bar, with itstop edgeconcave, and mounted on the carriage torise and Jfall therewith, by the `following mounting. The sha-per plateis shown-as closely adjacent the outer side ofthe suctionrhead butmounted independently-on the carriage.

The lower end of the sh aper 26 is shown as enclosed between Va smallupright fork 55 and the upper portion of a yoke 56, all three of themunited by a shouldered bolt which holds the fork rigid with the yoke,but permit-sa slight lateral play of the shaper, limited however by apin projecting from the shaper between the arms of the fork. The lowerend of the yoke is rigidly bolted to the upper end of a plunger 57having a frontwardly ex-l tended head overlyingv a horizontal portion ofthe carriage 28 and having an interior rod extending-within a recess in.the carriage, as'

seen in Fig. 3, with a strong compression spring58 confined below theplunger, tendlng to lift 1t relatively to the carriage, and

thus holding the'shaper in its operative posi-V tion, under the controlof a limiting bolt 59. By this arrangement theshaper is made to rise andfall with the carriage, in a substantially rigid manner, but thestrongspring 53 permits a slight downward yielding or cushioning withoutdetracting from the effectiveness of the pressure on the headband, andthe relation with the fork member 56 per- Thev manual adjustment of theleft carriage28 is made by shifting the collars 32, as already mitting,a slight transverse play assisting the shaper to adapt itself to thecurvature of the book, the fork also serving as a convenient means forconfining and initially adjusting a suction opening or nozzle 60 for theheadband, arranged at the top side of the holder, which has a horizontalextension or shank 61 constructed with an air channel62 leading to thesuction opening.A The holder shank 61 is connected by a hollow pivot orstud 63'with the upper portion of the carriage 28, which is providedwith extension side plates 64 to enclose the shank and. aiford bearingfor the stud. Y

The suction nozzle 60 is for the purpose of holding securely each smallheadband during and after severance and up to the time of application tothe book. As books may have varying thickness the nozzle opening ispreferably adjustable in length and :tor this purpose a narrow slide 66is arranged in a groove t at the top side of the holder, so that it canbe adjusted more or less in or out and thus brings the headband to thebook the book acts as a stop and on continued rise of the carriage theholder 27 yields relatively downward, while the concave shaper 26continues to rise and to press the headband firmly into contact aroundthe back of the book, the suction having ceased as the headbandcontacted the book. The holder spring 67 is of far lighter effect thanthe shaper spring 58, the function of the holder being completed whenthe headband meets the book, while the function oi the shaper is toafford strong pressure thereafter.

The suction action and control may be substantially asr follows. Apneumatic hose 72 is shown extending from each of the hollow studs 63 ofthe respective suction holders downwardly to a common pipe 73 which inturn is shown connected to a pipe 74 which extends toward the back ofthe mechanism and is connected by a pipe 75 with a control valve 76. Thecontrol valve may be substantially similar to that shown in said priorapplication at Figs. 12 and 13, comprising a sliding bar orhorizontal'plate 77 having a suction passage open in one position and arelief passage open to the atmosphere in anconnect the vertical pipe 7 5with a pipe' 80 leading to an air pump. l

rlhe stem 82 of the valve slide is indicated as being pressedbackwardly, or to the right in Fig. 3, by a spring 83 acting upon thehead 84 of the stem, `this head sliding in a fixed part and carrying a.cam roll 85 ybearing against the periphery of a cam 86 on the main shaft19. ln the position shown in Fig. 3 the valve is thrust frontwardly andthe suction is in effect, holding theA headband upon the holder. c

The various trains of connections are not shown in correspondingpositions in the several hgures, but each train from the shaft cam tothe terminal instrument is completely shown, andthe description givesthe order or cycln of operation, so that one versedin the art cancorrectly design the operating cams and attach them to the main shaft incorrect j relation.

The bodily lifting and lowering of the headband applying devices may beeffected blade by the applierand headband in as follows. theirextensions 29 and 20a with hubs 30 and 30a are supported in uprightposition on the horizontal axle system 31-34 already described. This isa floating axle mounted at the front or` swinging ends of lever arms 90fulcrumed on the axle 45, which axle. may act as a rock shaft, having arearwardly extending rock arm 91 carrying a follower or roll 92 bearingagainst a cani 93 on the main shaft 19. The axle part 31 is fixedagainst rotation in the left lever arm, being internally threaded andacting as a fixed nut for the threaded extension 35 of the axle part 34,which latter turns in the forked end of the right lever arm, and has akeyway by which the sprocket 48, between the fork ends, main` tains asliding keyed engagement with the axle.

ln the position shown the front ends of the arms 90 are in downwardposition, the cam roll being in lifted position, and a spring 94 may bearranged at each side to hold the parts in this position, with the'rollpressed against the cam, and the cam being adapted upon furtherrotation, to force down the roll and thereby lift the front arms, thecarriages and the headband applying devices, to place the headbands uponthe exposed back of the book.

Preferably the applying devices, the Shaper and the holder, assume aback position during the reception and severing of headbands, but withthe carriages shift or swing frontwardly therefrom during the risingmotion to apply the headbands to the book. This permits the shearingtype of severing device to be used, and avoids confiict with the frontthe lifting motion.

The following described device may be employed to cause' the frontwardswinging of the carriages during their elevating moverEhe carriages 28Vand .28a and ment. In a boss or enlargement formedY at the lower partof each carriage, at the top of the extension arm 29 or 29, is mounted abolt or stud 99 extending rearwardly, the rear Y end of each, 4boltcarrying a follower or roll100 adapted tok move along the surfaceofafixed cam 101. Each of the cams .101"is ofY substantial width, as seenin Fig. 2 so as to cooperate with the follower inall :adjustments forbook length, and each cam has a lower and an upper surface, Vwith adecided incline between them', so that in rising from the head` bandreceiving position the carriages andV and under a guard plate 105 andthence up-V wardly and rearwardly, each passing around an idler pulley106 or 106a. The feeding devices at the forwardv and rearwardV ends aresubstantially duplicated, the former carry! ing similar referencenumbers sometimes with the exponent a, and each set being adjustableindependently and in a dierent manner from the other set. Theconstruction of the forward set will be first described.

The idler 106a may constitute a guide pulley, with flanges, steering theheadband strip correctly to the feed rolls, and itself adjust? ablelongitudinally for this purpose. The headband passes from the'guidepulley horizontally frontward between a lower feed roll 108a and anupper feed roll 109, The lower feed rolls may be mounted upon so as toturn with a shaft 110 and may adjustably Vslide thereon, while the upperfeed rolls are mounted upon a shaft 111 on which they may slide. Asshown in Fig. 3 the upper shaft 111 may be mounted on rock arms 112having a fixed fulcrum 113 permitting the upper feed rolls to be liftedbodily at will for insertion of headband strip, gravity normallyholdingv them down upon the lower rolls.

The rearward or left pair of rolls 108, 109

are adapted to be adjustably shifted bodily along the direction of booktravel by means of. the threaded shaft 51 manually rotatable to give anadjustment to correspond with the position of the rear end of the bookdetermined by the position of the clamp pin l5. The connections for thisadjustment may comprise grooved hubs 115 on the feed rolls,

with fingers 116 engaging them extending from the adjusting or knifecarriage 137 to be described. y Y v Likewise the forward or right feedrolls 108% 109a are adapted to be bodily shiftable along the directionof book travel, by means of the threaded shaft 37 turned by the handwheel 38, Whi ch also has'sprocket connections for readjustinglengthwise the position of the carriage and headband applying device.The connection by which the shaft 37 effects the adjustment oftheforward feed rolls may comprise grooved hubs 115a on the feed rolls withfingers 116a enaging them, extending from the carriage137a tobedescribed.

In order to turn in unison the two'feed shafts 110, 111 they are shownat the left end as provided With intermeshing gears 121, 122. Byrotating the shaft 110 all `of the feed rolls are turned in unison. Thisactuation-,may be substantially asin said prior application, and brieflyreferred toras follows. Loose on the shaft 110 is indicated a gear 124constituting one member of a roller clutch or one-way drive device, theother `member consisting of a 4clutch member 125 fast on the shaft 110.Below the toothed clutch member 124 is a horizontal rack 126vreciplrocable to oscillate. the clutchrmember, thereby causingintermittent forward rotation of the shaft 110 and the four feed rollsfvThe parts thus far described are shown'in Fig. 2. The rack has arearward extension 127 shown'in Fig. 3, this being moved forwardlyandrearwardly. by an upright rock lever 128 fulcrunied on a rock shaft129 which `cai-rieL-z also a cam arm 130 at the extremity of .which is afollower or roll 131 engaging a cam 132 on the main shaft 19. A spring133 is `arranged to pull frontwardly on the rock lever 128 therebyholding the cam roll to the cam.

With this arrangement each rotation of the cam moves the rack126backward and front-f ward by a predetermined extent, thebackward'movement bythe cam operating to Arotate the feed shafts androlls and thereby advance on to the appliers suicient strip to form newheadbands, the return movement of the rack by the spring 133 being idleon 'account of the character of the drive clutch. "The'feed for theheadband strips is to be timedv to be completed before suction is.applied to the holder and before the operation of the severing devices.Adjustment of the'extent of feed and length of headband may: be eectedby a stop rod 134, seen in Figsy2^and 3, its threaded front end turning.in affixed nut or sleeve 135, so that by a suitable handle the rod maybe adjusted, for example backwardly, or to the right in Fig. 3, so as tolimit and shorten the frontward movement ofthe lever 128 and thereby;reduce the return' bands. n 1 Y r f .For theV purpose of. accuratelyalining or .140 and an upper blade141, preferably the lower blade beingrelatively fixed on the carriage, while theupper lblade swingsdownwardly to sever or shear the-headband. The

Aswinging blade is pivoted to the fixed blade by a pivot device 142comprising spring means to maintain cooperating contact and pressure.The movable blades 141 have, each at its inner end, actuating pins 143,and these two pins are` shown as both engaged in the elongatedhorizontal greove 144 of a baror cutter .actuator 145. Y

The cutter actuator bar 145 is mounted atv the topend of a carrier orshank 146 slidable vertically in fixed guideways, thelower end of thesliding shank being curved backwardly'as seen in Fig. 3, and connectedby links or shackles 147 with the front en'd of la lever 148=fulcrumedon a-iixed axle'149, the rear swinging end of the lever carrying a rolll15'() f engaged .on the periphery of a cam'151 on the main shaft 19..The cam is shown as having elevated the roll an'd depressed the-carrierand actuator bar and thereby.` cut the headregistering each oftheheadbands with the disclosed. A.y movable registering device isemployed, `the same having a feeler or contact part adapted to'be movedinto contact Vwiththe endv of the book and so determine the lband uponthe applier as they come. to applying position .j 4 A While theregistering devices may take. different forms each of themisshown-as alever 170, extending substantially vertically, and arranged Vwith a`fulcrum171 near itsmiddle by which it is adapted tomove to 'and fromcontactwith-the book. For example the registering Vlever may be mountedupon the'headband' applier carriage 28,` so that the lever will bodilyrise and fall and swing frontward and back with theca'rriagel In thisway the -lever'is broughtto position where it can make contact with theend of the book', such contact being effected by swinging about its ownlfulcrumina'plane parallel to that of the book.
